Abstract
A method and an assembly for absorbing energy during an overload event. An energy absorber reduces loads on an object being transported on a loading unit during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber. Measurement values on the current state of the loading unit are sensed. A control device determines an overload event and a damping of the energy absorber is set to a high value after the detection of the overload event. The damping is maintained for a specified prolonged time period and controlled dependent on the measurement values during the overload event to increase the load for objects during the specified time period initially to a specified threshold load and after the specified time dependent on the measurement values detected during the overload event.
